a l 2,807,060 lice Patented Sept. 24, 1957 This invention relates to a new and improved window construction and more particularly to a double hung window having inner sashes for panes of transparent material and having outersashes for panes of transparent material or screen material to be used either as a storm window or as a screen.

A prime object of the present invention is to provide a window construction of this type combining a double hung window and a double hung storm window or screen which may be readily installed as a unit within the margin of a standard window opening in a building.

Another object of the invention is to provide a window construction of this type with sliding sashes which can be quickly and easily removed or tilted without any skill being required and without the necessity of tools of any kind and without marring or otherwise damaging the A further object of the invention is to provide a window construction of this type with sashes which can readily be removed from inside theroom.

Still another object'of the invention is.to provide a window construction of this type with improved means for holding the sliding sashes in moved adjusted position.

Yet another object of the invention is to provide a window construction of this type with removable upper sashes and with improved means for supporting the upper sashes.

It is further proposed to provide a window construction of this type with means in common for locking the sliding sashes in closed position and for locking said sashes in tilted position.

It is a further object of the invention to provide a friction device for holding the sliding sashes in moved position with means for adjusting the friction thereof.

A still further object of the invention is to provide a window construction of this type which is simple and rugged in construction and which can be manufactured and sold at a reasonable cost.

Referring to the drawings in detail, a window construction made in accordance with the present invention is shown in- Figure 1 and'comprises a window frame -1, preferably made of wood and which may be of any desired height or width. The frame consists of a header 2, main side jambs '3, 3, auxiliary side jambs 4, 4 inside the main jambs, and a sill 5, and supports the conventional upper and lower window sashes 6 and 7, respectively. The main jambs 3, 3 are of uniform thickness throughout their length, but the auxiliary jambs 4, 4 are stepped along their inner side surfaces, when seen in cross section, so that. they are thicker at their outer ends, that is, their outer vertical edges. Top andbottom outer face strips 8 and 9 are suitably fastened to the inner ends of the header and sill, respectively, and an inner top face rail 10 issecured to the outer end of the header. Vertical outer-side face strips 11 and 12 are fastened to the front ends of the side jambs 3, 3. p The face strips close. the junctures between the ends and sides of the frame. and the window opening.

The sashes 6 and 7 are preferably formed of wood and each consists of top and bottom cross rails 13 and 14,, respectively, and side rails 15 carrying a pane of glass 16.

The main side jambs 3, 3 of the frame are formed with opposed slots 17 along their inner surfaces extending the length thereof, and the sill 5, when seen in cross.

section, is stepped, the-inner step 18 forming a seat for the, bottom rail 14 of the lower sash 7, the coacting faces of the bottom rail and step providing a weathertight joint between the sill and bottom rail. L-shaped bars 19 are mounted in the slots 17, each bar having one wing 20 thereof embedded in its respective slot and the other wing 21 thereof extending along and contacting the inner surface of the stile along the groove or slot and being fastened at its ends to the stile by screws 22. V

In order to facilitate ready installation and removal of the lower sash 7, a sliding member comprising an elongated metal channel bar or shoe plate 23 is slidably mounted in the lower half of each slot 17 of the. stiles 3, 3. One wing portion or lateral flange 24 of the channel bar is slidable in the slot and disposed alongside the L-shaped bar -19 therein in a plane that is parallel with the general plane of the window frame, and its other wing25 is turned or folded upon itself, as indicated at 26. The folds are pressed together at their ends 27 leaving a narrow channel 28 opening outwardly of the frame between the folds from end to end.

An elongated metal mounting strip 29, U-shaped in along one edge thereof, said flange engaging the inner surface of the rail. Wing portion 32 is cut away at its top end to form a slanting edge 34 and terminates short of the bottom. end of the other wing portion 31 thereof.

where it is notched to form a pointed lug 35. The mounting strip extends the length of the side rail with the edge of its wing portion 32 facing inwardly of the frame and adapted to beinserted into and to become 'interlocked with the channel 28 of the sliding channel bar 23.

The connection between the lower sash 7 and "the sliding channel bars 23 is effected by first inserting the pointed lugs 35 of the mounting strips 29 on the side rails into the channels 28 of the channel bars at points just above the bottom pressed closed ends 27 of the bars, and then moving the wing portions 32 inwardly and downwardly of the channels to bring the lugs 35 behind the bottom closed ends 27 of the sliding angle bars, said 7 closed ends being adapted to serve as pivots during such movement. The sash 7 is thus interlocked with the sliding channel bars 23, and is held in vertical position in the window frame, with the inner ends of the auxiliary stiles 4, 4 serving as inner stops therefor, and the sash is adapted to slide up and down along the L-shaped bars 19 with the sliding channel bars. The top rail 13 of the sash serves as a handle for sliding it up and down.

The upper sash 6 is removably mounted in the window frame with its bottom cross rail 14 supported on shoulders or seats 36 at the lower ends of rabbets 37 on the inner surfaces of the auxiliary side stiles 4, 4, outwardly of the lower sash 7. Pins 38 are formed on the outer edge of the bottom rail 14 at the ends thereof and are adapted to project into notches 39 formed in the top ends of the posts in order to hold the sash against displacement. The top cross rail 13 of the sash projects partially into a channel or groove 40 formed on the inner surface of the header 2, leaving a clearance 41 thereabove.

The lower sash 7 may be locked in closed position and held against rattling by locking mechanism carried on the top cross rail 13 adjacent each end thereof. This mechanism includes an elongated metal latch member 42 pivotally fastened at its center to the top rail by a pivot pin 43 so that one end thereof is adapted to protrude beyond the side of the sash into the adjacent slot 17 in the stile 3. The other end of the latch member is formed with an elongated slot 44 to receive the end of a pin 45 projecting from the end of an actuating lever 46 pivotally mounted on the adjacent side rail 15 of the sash by 'a pin 47 and normally extending at right angles to the latch member so that the latch member can be swung in one direction into the adjacent slot 17 and become jammed between the embedded sliding angle bar 23 and the wall of the slot for frictionally locking the sash against movement.

An important feature of the presentinvention is improved mechanism for holding the lower slidable sash 7 in moved adjusted position and against sliding in the frame under gravitional action. As shown in detail in Figures 9 and 10, this mechanism is mounted in a chamber 48 cut in the inner side surface of each main jamb 3 adjacent the slot 17 therein, at a point adjacent the top of the sash 7 when the sash is in closed position. The chamber extends through the wall of the slot opening outwardly thereinto. An auxiliary chamber 49 is cut in the inner side surface alongside of and opening in to chamber 48. The mechanism includes a metal casting or block 50 substantially rectangular in shape fitted in the chamber 48 and formed with a cutaway portion at its inner face forming a recess 51 therein to provide a raceway for a roller 52, and with a floor portion 53. The base 54 of the recess or raceway is tapered or inclined downwardly and inwardly toward the slot 17 in the jamb 3 so that the depth of the recess near its bottom is shallower than the diameter of the roller 52 whereby the periphery of the roller is adapted to protrude into the slot and frictionally grip the wing or flange 24 of the sliding channel bar 23 therein. Upward pressure on the sash 7 will cause the sliding channel bars 23 to force the rollers 52 upwardly in the recesses 51 thereby permitting the upward movement of the sash. Upon release of such pressure, any downward movement of the sash will cause the protruding rollers to frictionally grip the sliding channel bars and prevent further downward movement of the sash. The degree of protrusion of the roller 52 is adjusted by the shank of a screw 55 which projects through a screw threaded opening 56 in the casing 50 adjacent its bottom end and into the recess where it contacts the roller and forces it upwardly. The head 57 of the screw is housed in the auxiliary chamber 49 and is provided with peripheral sockets 58 to receive a tool for turning the screw. The chambers 48 and 43 are closed by a pivoted cover plate 59 secured to the stile.

The sashes 6 and 7 are removed inwardly of the room. Lower sash 7 is first removed by sliding the latch members 42 away from the slots 17 in the stiles 3, 3. The sash is then lifted slightly to retract the pointed ends 35 of the mounting strips 29 out of the closed ends 27 of the sliding angle bars 23 and to bring the bottom rail 14 of the sash clear of the sill 5 to permit the bottom end of the sash to be swung inwardly into the room as the mounting strips pivot on their upper ends and finally slide free of the sliding bars 23 for complete removal from the frame.

The lower sash 7 may be tilted by swinging its upper end inwardly around its bottom rail 14 as a pivot, and the sash is adapted to be held in such tilted position by swinging the latch members 42 into interlocking relation with keeper members 60 on the side face rails 11 and 12 of the frame midway their ends.

The upper sash 6 is removed by raising the sash slightly into the clearance 41 in the groove 40 of the header 2 in order to retract the fins 38 from the notches 39 in the posts 37, then swinging the bottom end of the sash inwardly as shown in Figure 8, and finally sliding the top rail 13 out of the groove 40 for complete removal from the frame.

According to the present invention, a storm window or screen assembly is positioned in the window frame 1 outwardly of the sashes 6 and 7. This assembly includes the auxiliary side stiles 4, 4 and a lower storm or screen sash 61 similar in construction to lower sash 7, and an upper storm or screen 62 similar in construction to the upper sash 6, similar reference numerals being used to indicate similar parts of the sashes.

The lower sash 61 is adapted to rest on the outer step 63 of the sill 5 and is slidable similarly to sash 7 in opposed slots 64 formed in the auxiliary stiles 4, 4. Sash 61 however is narrower than sash 7 so that it can be com pletely removed inwardly of the room in the manner of sash 7.

Upper sash 62 is supported on shoulders or seats 65 at the lower ends of rabbets 66 in the auxiliary stiles 4, 4, outwardly of the lower sash 61. The top rail 13 of the sash 62 extends partially into an outer groove 66 formed in the under surface of the header 2. Upper sash 62 is narrower than the other sashes so that it may be com pletely removed from the frame inwardly of the room in the manner of sash 6.

When the sashes are in closed position as shown in Figures 1 and 2, the upper rails of the lower sashes and the bottom rails of the upper sashes meet in interlocking relation thereby providing a weatherproof juncture at the meeting edges of the rails. It will also be noted that the top rails of the upper sashes extend into and are interlocked with the channels or grooves in the header 2 thereby protecting the window from the weather at the top. The bottom rails of the lower sashes coact with the stepped portions of the sill to protect the window at the bottom.

Preferably the stiles and rails of the sashes have grooves 67 disposed in a common plane in their inner faces, in which grooves the respective glass panes 16 are nicely slidable; and one of the sash rails, preferably the upper rail 13, is separably connected to the corresponding stiles as by mortised joints 68 and screws 69, the grooves 67 opening through the corresponding ends of the stiles, so that to insert a glass pane in a sash, the screws 69 are removed and the upper rail is disconnected from the stiles, after which the glass pane is slid edgewise into the grooves 67 of the stiles and bottom rail 14 and then the upper rail is again connected to the stiles with the upper edge of the glass pane seated in the groove 67 of said upper rail.

Changes in details of construction may be made within the principles of the invention.

What I claim is:

A window construction comprising a frame formed of side jambs, a header and a sill, said jambs having vertical longitudinal slots on their inner surfaces, channel bars having lateral flanges that lie in a common plane parallel to the general plane of said frame and are slidable in said slots, a lower sash interlocked with said channel bars so that the interlocked bars and sash may slide vertically in the frame, and means for holding the sash in adjusted position including a block in one of said jambs having an inclined surface facing said lateral flange of the corresponding said channel bar and a roller rollable along said inclined surface, said roller being arranged to protrude from said block into engagement with said flange of said channel bar.
